Which of the following most logically completes the argument?

Sviatovin is a medieval Moringian text whose author and exact date of composition are unknown. However, the events in the life of Prince Sviatov that the text describes occurred in 1165, and in the diagram of Sviatov's family that accompanies the text his father, who died in 1167, is identified as still living. Thus Sviatovin must have been written between 1165 and 1167, assuming that

题目:

Cognitive scientist: Using the pioneering work of comparative psychologist Gordon Gallup as a model, several studies have investigated animals’ capacity for mirror self-recognition (MSR). Most animals exposed to a mirror respond only with social behavior, such as aggression. However, in the case of the great apes, repeated exposure to mirrors leads to self-directed behaviors, such as exploring the inside of the mouth, suggesting that these animals recognize the reflection as an image of self. The implication of these studies is that the great apes have a capacity for self-awareness unique among nonhuman species.

The cognitive scientist makes which of the following assumptions in the argument above?

选项:

A、Gallup's work has established that the great apes have a capacity for MSR unique among nonhuman species.
B、If an animal does not have the capacity for MSR, it does not have the capacity for self-awareness.
C、If a researcher exposes an animal to a mirror and that animal exhibits social behavior, that animal is incapable of being self-aware.
D、When exposed to a mirror, all animals display either social behavior or self-directed behavior.
E、Animals that do not exhibit MSR may demonstrate a capacity for self-awareness in other ways.

文章:

Solar ponds are bodies of water in which circulation is incomplete and there is a very high salt concentration that increases with depth.  This vertical change in salinity serves to trap heat because concentrated brine in the lowest water level acts as a collector and storage area for solar heat, while the less saline, lighter water at the upper levels provides insulation.  Heat is thus retained in the depths.
 
An artificial pond of this type has been constructed on the western shore of the Dead Sea in Israel in order to test its suitability as a source of low-grade heat for conversion into electricity.  An immediate threat to the success of the venture was the growth of algae.  Water in solar ponds must be kept maximally transparent to allow penetration of light to the deep storage area.  Therefore, any particles of matter in the water, such as algae cells, that scatter or absorb light will interfere with the collection of heat.
 
One proposed method of controlling the algae was the application of an algicide.  However, the Dead Sea is a closed body of water without any outlet and as such is very easily contaminated.  Extensive use of chemicals in numerous future full-scale solar ponds would lead to such contamination of the Dead Sea, which now enjoys a lucrative tourist trade.
A recent experiment has supplied a more promising method for controlling the algae.  To repress the algae cells' capacity for accommodating themselves to environmental changes, the water in the solar pond was first made more saline through evaporation and then diluted by a rapid inflow of fresh water.  This shock reduced the cells' ability to regulate the movement of water through their membranes.  They rapidly absorbed water, resulting in distortions of shape, increase in volume, and impairment to motility.  Their buoyancy adversely affected, the cells sank to the bottom of the pond, where they encountered the hot waters of the storage layer and were destroyed.  This method allows for effective control of nuisance algae while leaving solar ponds as one of the cleanest technologies providing energy for human use.

题目:

Which of the following, if true, would seriously undermine the validity of the conclusions drawn from the experiment described in the last paragraph of the passage?

选项:

A、The algae cells that sank to the bottom of the pond were destroyed only after a time lag of twenty-four hours.
B、The lateral motility of the algae cells that sank to the bottom of the pond was not impaired.
C、The water with which the artificial solar pond was diluted contained microorganisms that kill algae.
D、The algae cells that sank to the bottom of the pond were actually killed by the rapid change in pressure.
E、The higher salinity brought about through evaporation increased the transparency of the upper levels of water in the pond.

文章:

    In 1675, Louis XIV established the Parisian seamstresses' guild, the first independent all-female guild created in over 200 years. Guild members could make and sell women's and children's clothing, but were prohibited from producing men's clothing or dresses for court women. Tailors resented the ascension of seamstresses to guild status; seamstresses, meanwhile, were impatient with the remaining restrictions on their right to clothe women.

    The conflict between the guilds was not purely economic, however. A 1675 police report indicated that since so many seamstresses were already working illegally, the tailors were unlikely to suffer additional economic damage because of the seamstresses' incorporation. Moreover, guild membership held very different meanings for tailors and seamstresses. To the tailors, their status as guild members overlapped with their role as heads of household, and entitled them to employ as seamstresses female family members who did not marry outside the trade. The seamstresses, however, viewed guild membership as a mark of independence from the patriarchal family. Their guild was composed not of family units but of individual women who enjoyed unusual legal and economic privileges. At the conflict's center was the issue of whether tailors' female relatives should be identified as family members protected by the tailors' guild or as individuals under the jurisdiction of the seamstresses' guild.

题目:

The author mentions the seamstresses' view of guild membership as a "mark of independence from the patriarchal family" (the highlighted text) primarily in order to

选项:

A、emphasize that the establishment of the seamstresses' guild had implications that were not solely economic
B、illustrate the conflict that existed between tailors and their female family members over membership in the tailors' guild
C、imply that the establishment of the seamstresses' guild ushered in a period of increased economic and social freedom for women in France
D、provide an explanation for the dramatic increase in the number of women working as seamstresses after 1675
E、indicate that members of the seamstresses' guild were financially more successful than were tailors' female relatives protected by the tailors' guild

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.

A photography dealer ordered 60 Model X cameras to be sold for $250 each, which represents a 20 percent markup over the dealer's initial cost for each camera. Of the cameras ordered, 6 were never sold and were returned to the manufacturer for a refund of 50 percent of the dealer's initial cost. What was the dealer's approximate profit or loss as a percent of the dealer's initial cost for the 60 cameras?
